Identifying factors that impact physical function in older populations is important for the maintenance of good health with aging. Age-related hyperkyphosis, an excessive curvature in the thoracic spine, affects up to 40% of the older adults and is more common in older females than males. An association of age-related hyperkyphosis with impaired physical function has been reported in numerous studies, however, other studies have reported that a greater magnitude of kyphosis did not associate with impaired physical function. Given the inconsistencies regarding the impact of hyperkyphosis on physical function, the purpose of our study is to perform a systematic review of the existing studies in order to better describe the association between hyperkyphosis and physical function. Prospective and retrospective cohort, case-control, and cross-sectional studies which measure physical function by valid functional tests and questionnaires in older females will be included. We will search Scopus, ISI Web of Science, Cochrane Library, PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL) and PEDro databases. Studies will be searched and then selected by two independent reviewers based on quality assessment tools from the National Heart, Lung, and Blood Institute (NHLBI). A meta-analysis will be conducted if data reported for individual studies allow. Specifically, if two or more individual studies provide measures of central tendency and variability from any of the categories of physical function measures, data will be gathered for meta-analysis. If a meta-analysis is not possible, data will be synthesized and described in a narrative form by size and variability of effect, direction of effect, and association with hyperkyphosis.
确定影响老年人群身体功能的因素对于维持老年人的健康非常重要。年龄相关性脊柱后凸过度，即胸椎过度弯曲，影响多达40%的老年人，且在老年女性中比男性更常见。许多研究报告了年龄相关性脊柱后凸过度与身体功能受损之间的关联，然而，其他研究报告称更大程度的脊柱后凸与身体功能受损并无关联。鉴于关于脊柱后凸过度对身体功能影响的研究结果不一致，我们研究的目的是对现有研究进行系统综述，以便更好地描述脊柱后凸过度与身体功能之间的关联。将纳入通过有效的功能测试和问卷对老年女性身体功能进行测量的前瞻性和回顾性队列研究、病例对照研究及横断面研究。我们将检索Scopus、科学引文索引（ISI）Web of Science、Cochrane图书馆、PubMed、护理学与健康相关文献累积索引（CINAHL）和PEDro数据库。研究将由两名独立评审员根据美国国立心肺血液研究所（NHLBI）的质量评估工具进行检索和筛选。如果各独立研究报告的数据允许，将进行荟萃分析。具体而言，如果两项或更多独立研究提供了身体功能测量任何类别中的集中趋势和变异性测量值，将收集数据进行荟萃分析。如果无法进行荟萃分析，将按效应大小和变异性、效应方向以及与脊柱后凸过度的关联，以叙述形式对数据进行综合和描述。
